+U-Boot for the Congatec QMX6 boards
+
+This file contains information for the port of U-Boot to the Congatec
+QMX6 boards.
+
+1. Building U-Boot
+------------------
+
+- Build U-Boot for Congatec QMX6 boards:
+
+$ make mrproper
+$ make cgtqmx6eval_defconfig
+$ make
+
+This will generate the following binaries:
+
+- SPL
+- u-boot.img
+
+2. Flashing U-Boot in the SPI NOR
+---------------------------------
+
+Copy SPL and u-boot.img to the exported TFTP directory of the
+host PC (/tftpboot , for example).
+
+=> sf probe
+
+=> setenv serverip <server_ip_address>
+
+=> setenv ipaddr <board_ip_address>
+
+=> tftp 0x12000000 SPL
+
+=> sf erase 0x0 0x10000
+
+=> sf write 0x12000000 0x400 0x10000
+
+=> tftp 0x12000000 u-boot.img
+
+=> sf erase 0x10000 0x70000
+
+=> sf write 0x12000000 0x10000 0x70000
+
+Reboot the board and the new U-Boot should come up.
+
+3. Booting from the SD card
+---------------------------
+
+- Flash the SPL image into the SD card:
+
+sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync
+
+- Flash the u-boot.img image into the SD card:
+
+sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync
+
+- Insert the SD card into the big slot.
+
+The boot medium of Congatec QMX6 boards is the SPI NOR flash, so boot
+the board from SPI first.
+
+It is also possible to boot from the SD card slot by using the 'bmode'
+command:
+
+=> bmode esdhc4
+
+And then the U-Boot from the big slot will boot.
+
+Note: If the "bmode" command is not available from your pre-installed U-Boot,
+these instruction will produce the same effect:
+
+=> mw.l 0x20d8040 0x3850
+=> mw.l 0x020d8044 0x10000000
+=> reset
